An octagonal microstrip
patch antenna is presented in this paper. A small sized microstrip patch
antenna with a high gain has been the focusing point of so many researches over
the years. Microstrip patch antenna is basically known to have a low gain as a
result various techniques are carried out in order to enhance the gain. In this
work, a single patch octagonal microstrip patch antenna and a 1x2 octagonal
patch antenna array are designed and the effects are studied. The structure is
designed on four different substrates FR4, Duroid, Arlon and Rogers substrate
materials. Copper is used as the patch and ground material. The antenna is
designed on a small substrate material and it is probe fed. The simulated
results of the array reveals a gain increase of 6.25dB from 3.6dB of the single
patch on the FR4 substrate. The simulated results of the antenna in terms of
reflection coefficients, voltage standing wave ratio (VSWR) and gains realized
showed that the antenna has prospective applications for 4.6 and 5.9GHz
applications. Conclusively, the antenna with the FR4 substrate shows the best
antenna performance in terms of Gain and Return loss and its operating
frequency falls under the WiMAX and WLAN range compared to the other
substrates. The tool used for the design and simulation is the Computer
Simulation Technology (CST) microwave studio.
